Here is a charity sale（义卖）for the poor kids in the mountain area. We’ll give away the money we raise in the charity sale. Come and see our things.
Li Hua | I have an MP4 player. I have had it for a year. It still works very well now. And I have downloaded （下载） some pop songs in it. I hope it can be with you when you are unhappy. It costs 300 yuan. Now you can pay 50 yuan for it. |
Hu Ming | I’d like to sell some of my story books. I started to buy the story books when I was ten years old. I believe anyone like me will learn a lot from these books. Each book only costs 10 yuan. Come and buy them! |
Wang Hao | I have some soft toys to sell. The toy bear is my thirteen-year-old birthday present. It still looks very new. It costs 50 yuan. You only need to pay 15 yuan for it now. Other toys are very new but cheap, too. |

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
